Python program to print the Inverted heart pattern

Let us see how to print an inverted heart pattern in Python.

Example:

Input: 11 Output: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* ********************* ********* ******** ******* ****** ***** **** Input: 15 Output: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* ********************* *********************** ************************* *************************** ***************************** ************* ************ *********** ********** ********* ******** ******* ******

Approach:

1. Determine the size of the heart.
2. Print an inverted triangle with size number of rows.
3. Print the rest of the heart in 4 segments inside another loop.
4. Print the white space right-triangle at the beginning.
5. Print the first trapezium with stars.
6. Print the white space triangle.
7. Print the second trapezium with stars.

# determining the size of the heart size = 15 # printing the inverted triangle for a in range(0, size): for b in range(a, size): print(" ", end = "") for b in range(1, (a * 2)): print("*", end = "") print("") # printing rest of the heart for a in range(size, int(size / 2) - 1 , -2): # printing the white space right-triangle for b in range(1, size - a, 2): print(" ", end = "") # printing the first trapezium for b in range(1, a + 1): print("*", end = "") # printing the white space triangle for b in range(1, (size - a) + 1): print(" ", end = "") # printing the second trapezium for b in range(1, a): print("*", end = "") # new line print("") 

Output:

 * *** ***** ******* ********* *********** ************* *************** ***************** ******************* ********************* *********************** ************************* *************************** ***************************** ************* ************ *********** ********** ********* ******** ******* ******

 Time complexity: O(S²) for given input size S

Auxiliary Space: O(1)
